AUTOMATED BLIND COEFFICIENT CONTROL IN ANALOG ACTIVE INTERFERENCE CANCELLATION

摘要

Aspects of the disclosure are directed to interference cancellation and wireless communication. An analog active interference cancellation circuit may be configured to cancel in-device interference corresponding to transmissions from a transmitter at a wireless communication device, which affects the performance of a receiver at the wireless communication device. The interference cancellation circuit may be configured according to one or more digital coefficients calculated based on a baseband downconverted from the RF output of the receiver. That is, the digital coefficient may be converted to an analog coefficient and applied to the interference cancellation circuit.
